LIFE-SAVING DEVICE.

Specification of Letters Patent.

Patented June 8, l 909.

Application filed September 14, 1908. Serial No. 452,822.

To all whom 'it may concern:

Be it known that l, Fnnomncit (J. BARGAR, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Life-Saving Devices, of which the following is a specification.

My invention relates to the improvement of life saving devices of that class which are adapted to be used to prevent drowning.

The objects of my invention are to provide a simple and inexpensive although effective life saving device of this class, of a construction which permits of its being secured to the body of a person or carried in a convenient manner. 1

My invention further consists in details of construction and arrangei'nen't of parts which will be more fully pointed out hereinafter.

These objects I accomplish in the manner illustrated .in the accompanying drawing, in which:

Figure 1 is a view in perspective of my improved life saving device, showing the lower portion of the gas bag broken away on one side for the sake of convenience in illustration, Fig. 2 is-a central vertical section of the same, and, Fig. 3 is an enlarged sectional view on line of Fig. 2.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention, Iemploy a suitable casing of receptacle 1, whichis preferably of the partially flattened or oblong.

form shown more clearly in Fig. 3 of the drawing, and which on one side is concaved orinwardly curved as indicated at 1 to facilitate the fitting of the same to the body of the wearer. The casing or receptacle 1 has its lower end perforated as indicated at 2 and its upper open end formed with a tapering 01' inwardly inclined extension 2. In the construction of the casing 1, I preferably form the same at the junction of its extension 2 and. the body, with a peripheral. projection or shoulder 3.

4 represents a gas bag which may be formed of any desired shape and of any suitable or well known gas tight and waterproof niateriah The gas bag 4: has its reducedaopen end" or neck portion secured about the upper portion of the body of the casing 1, this being preferably accomplished by the employment of a close fitting band 5 AVlllCll embraces the neck termination of the gas bag innnediately below the shoulder projection 3 of the casing. It is obvious, ho\\'- ever, that other suitable means may be employed for attaching said gas bag tolhe casing at the point mentioned. The casing or receptacle 1 is designed to be partially tilled with calcium carbid as indicated at (i and such carbid may be employed therein in a loose state as shown, or may be contained in a suitable fabric sack or cover;

In utilizing my device, the uninflated gas .bag may be suitably folded and secured about or above the casing 1 in compact form and the casing may be strapped or otherwise suitably bound to the wearer preferably be neath the outer clothing. Assuming that the wearer of my device is through accident or otherwise, cast into the water and unable to swim to a place of safety, it will be run derstood that the water rising in the casing 1 through the perforations and coming into contact'with the carbid, will result in the generation of gas, which will pass outward through the reduced upward extension 2* of the receptacle into the gas bag and operate to inflate the latter. The wearer during this operation, may remove the casing from its connection with his body or clothing and by grasping the casing with one or both hands, will be preventedfrom sinking, owing to the buoyancy of the inflated gas ag.

The formation of the casing with the inwardly inclined and reduced outlet 2*, tends to prevent a direct contact of the gas generated in the casing 1, with the material forming the gas bag, thereby obviating the danger of said bag being burned or in ured by the heat of the It will be understood from the construction described, that my invention is compa'ratively simple and inexpensive and that by its use a. person grasping the same and holding the casing in a substantially upright position, may be prevented from sinking without additional effort on his part, for a. considerable period of time.

\Vhat- I claim, is: i 1. In a device of the character described, the combination with a casing one side of which is concaved to conform to the shape of the body of the wearer, of an outwardly extending flange around the upper portion of said casing, and an inwardly directed neck portion 2 above said flange, a gas bag and means for binding the material of said Iii) Ion

lit-n gas bag ai'ouudsaid casing beneath said flange.

In a life saving device. the combination with a casing of elongated or flattened torn-i in cross section. said casing having a perforated lower end and an open upper end. of a gas-tight hing of waterproof material, andnieans for binding the mouth of said l a; about the upper portion of said casing.

:3. In a life saving device. the combinalion with a easing having a perforated t underside and having its upper open end formed with an inwardly tapered extension, I of a gas bag adapted to have its mouth portion seem-ed about the body of the casing 15 below said extension. i In testimony whereof I aflix my signature t in presence of two witnesses.
